Application filed August 4, 1914. Serial No. 854,978.

To all whom it may concern Be it known that l, EDWARD G. HAYNE, acitizen of the United States, residing at Ottawa, in the county of LaSalle and State of Illinois, have invented certain new and usefulImprovements in Devices for Milkng Cows; and I do hereby declare thefoliowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to devices for milking cows, and in particular todevices whereby the procem of milking can be accomplished in a perfectlywholesome and sanitary manner.

One of the objects of my invention is to provide a device whereby thecow can be manually milked in the ordinarymanner in such a way thatbacterial laden air is excluded from the milk.

A still further object of my invention is to provide a device wherebythe teat or glove covering the teat of a cow can be rig idly attached inposition by the fingers of the operator.

With these and other objects in view to be developed as thespecification proceeds I shall now describe my invention in which apreferred form is shown in the drawings, but l wish it to be understoodthat l am not limited to the form of structure shown but claim allpossible modifications which fall within the scope of the claim appendedhereto.

Similar characters of reference refer to similar parts throughout thedrawings, in

which,

Figure 1, is a perspective view of my device in assembled formation.Fig. 2, is a sectional view through the teat or glove. Fig. 3, is a planview thereof. And Fig. 4, is a view of a modified form.

Referring to Fig. 1 of the drawings, ll use an air tight receptacle'l,said receptacle having a lifting handle 2, riveted thereto, a fillingopening thereto adapted to be closed against the intrusion of air afterthe can has been filled with milk, and a check controlled valve 3.adapted to allow the air within the can to escape as it is filled withmilk, and to check the ingress of air. A suitable supply tube 4 isconnected to the filling opening of the can and adapted to supply milkthereto. said supply tube 4 having a plurality of branch tubes 5 bag anozzle end 6 adapt ed to seat over the mouth 'Z of the teat or glove 8,said teat or glove'being adapted to.

cover the teat of the cow in such manner that air will be excluded fromreaching the milk.

my neck portion 10 a plurality of apertured tongues 11, said tongueshaving a central aperture 12 therethrough' of a diameter large enough toreceive the ends of the finger of the operator, said tongues being ofthe same thickness and strength with said neck and body portion.

In the modified form shown in Fig. 4:, 13 is a top plate havingdownturncd edges 14. a plurality of projections 15, and an offsetportion 16 adapted to seat the head of a bolt. while the lower plate 17has an upturned flanged edge 18 adapted to seat within the flange 14 ofthe upper plate and to seal therebetween a washer 19, the plate 17 hasan outlet 20 communicating with the receptacle 1. There is a centralaperture 21 therethrough, through which the bolt 22 is passed to locksaid plates 13 and 17 into operative position by means of the nut 23.The mouth 7 of each teat glove is mounted upon one of the projections 15andis operated in the before described manner.

in mounting the glove upon the teat of the cow, the operator inserts twoof his fingers in the apertures 12, with one hand and grasp the othertongue with. the opposite hand and at the same moment stretching alltongues outwardly to open the neck portion 10 of the glove or teat. Whenin open position the glove is inserted to fully cover the teat when thetongues are allowed to respond to their normal position, thereby closingthe restricted neck portion 10 to bind against the teat, this operationcombining to retain the glove or teat upon the teat and to exclude airtherefrom. The cow is then milked by hand in the usual customary manner,the milk flowing through the tubes 5 and 4 into the can 1 where it canbe retained to an unusual length of time without souring owing to thefact that the air has been wholly excluded from the milk, so that thebacteria will not penetrate the milk and thereby sour it.

prising; a sealed receptacle, a supply tuhe communicating thereto, a,union receptacle connected to sand supply tube having a plurelityot'projections therefrom, and a test 4 glove mounted upon each of seidprojections, said union receptacle comprising, an upper plate havingdownturned edges, a plurality of integral projections erising therefrom,and e squared ofitset portion centrelly disposed therein, a lower platehaving upturned edges, an outlet therefrom and centrally eperturedtherethrough, and a loolt having" a, squared head snugly seated inotiset portion and passing through said enerture to mount said platesinto operative position, the setting of said head preventing the turningof said bolt and the consequent loosening of said device.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing Witnesses.
